Question

For the diagram shown above, $\angle 3\&$are alternate interior angles while $\angle 3\&$ co-interior angles.

• A. $\angle 6$
• B. $\angle 5$
• C. $\angle 7$
• D. $\angle 8$

Answer 1

Answer: (A), (B)

$\angle 5$

Concept:

Alternate interior angles are angles formed when two parallel or non-parallel lines are intersected by a transversal. And Co-interior angles are the pair of non-adjacent interior angles that lie on the same side of the transversal.

Here, from the diagram shown:
$\angle 3$ and $\angle 5$ are alternate interior angles.
While $\angle 3$ and $\angle 6$ are co-interior angles.
